@Igor_De : this is a well known limitation caused by interaction with seam line. ;)
If you need more information or think there is more to do, please open a forum topic according guidelines in the big yellow box on top of the page. Thanks. :)

If it is a "well known limitation" - it shold not completly crash software ;-)
Just show message: "Impossible"

@openBrain do you know if this is listed in the Known Issues thread, btw?
Is there a ticket open for this crash bug already ?

@Kunda1 : 0002715, 0003436, 0004076 IMO describes the exact same issue.
0003310, 0003970, 0003977 may be same kind of issue.
0003142, 0003554 describes other known limitations of (tricky) fillet/chamfer tools.
Unfortunately I think all cases are OCC issues. :/

@Igor_De : this is sensible but not so simple. 0003436:0012736 can be of interest for your understanding. FC uses external pieces of software, especially OCC as a geometric kernel. Limitations (as cases where they appear) are multiple. Raising a ticket for each basically clutters the tracker, that's why we ask you to post to forum first. In this case, your file would probably has been added to an existing ticket as test case. ;)
Notice that refining your model before filleting solves the issue. :)

Thanks a lot (for detailed answer and for Freecad).
Sorry for delay - I had no time for answer.
And sorry for troble - my English is still not so fluent.
I am novice in Freecad, but not in design.
I studied russian lessons and articles.
It makes me cry (it looks like mind masturbation).
So, I am going to make good manuals/lessons for russian language.
That was the reason for this ticket.
  
Let's close this ticket (I have no rights to change ticket state).
